...they are to each other inverfely as the diftances of their directions from the axis of the engine ; or when the power is to the weight, as the radius of the roller to the radius of the wheel, the power being fuppofed to a<ft in a perpendicular to this radius...

...lower block. XXIX. On a fyftem of moveable pullies, in which a feparate firing goes round each pully, there will be an equilibrium when the power is to the weight, as unity to that power of two of which the index is the number of moveable pullies. It is to be obferved...

...concerning this plane will principally apply to the line when in this lituation. When fo fituated, there will be an equilibrium, 'when the power is to the weight as the height of the plane is to it's biife. In other words, the mechanical advantage is in proportion as...

...body is drawn, is in the direction D e, parallel to the inclined plane. When thus fituated therefore, there will be an equilibrium, when the power is to the weight of the body, as the height of the plane is to its bafe. In other words, the mechanical advantage gained...

...«.m in peritroctiio. PROPOSITION XXXVIII. 154. There will be an equilibrium in the icheel and axle, when the power is to the weight as the radius of the axle to the radiui of the wheel. It is of no consequence whatever, whether the axle and wheel be in the...

...the radius of the wheel, is applied at the distance of that radius : therefore, Prop. LII. there is an equilibrium, when the power is to the weight, as the radius of the roller to the radius of the wheel. / COR. i. Hence it is evident, that by increasing the diameter of...

...its operations arc quick, and it is exerted or resides in a small compass. In every species of lever there will be an equilibrium, when the power is to the weight as the distance of the weight from the fulcrum is to the distance of the power from the fulcrum. Effects of...

...the axis. ON THE WHEEL AND AXLE. PROP. XVIII. (96.) There is an equilibrium upon the wheel and axle, when the power is to the weight, as the radius of the axle to the radius of the wheel. The effort of the power to turn the machine round the axis, must be the...

...Mechanical Powers. Definition of Wheel and Axle. Prop. 10. There is an equilihrium upon the wheel and axle when the power is to the weight as the radius of the axle to the radius of the wheel. I >if iiiiri.m of pulley. Prop. 11. In the single moveahle pulley where...

...the nail by the time that the nail is drawn out Hence it is evident, that in every species of lever there will be an equilibrium, when the power is to the weight as the distance of the weight from the fulcrum is to the distance of the power from the fulcrum. In experiments...
